This invention relates to improvements in pipe hangers or brackets of wall type, and the object of the invention is to provide a simple, inexpensive and efficient hanger which will permit free movement of the pipe in contracting and expanding with changes of temperature, in such a way that the hanger is relieved of all stresses other than V the weight of the pipe.

It has been found with hangers of ordinary construction that a very considerable frictional grip exists between the hanger and pipe, so that as the pipe expands or contracts with changes in temperature, a very considerable lateral force acts on the hanger. In some instances, where the pipes are of sufficient length and considerable frictional contact exists between the hanger and pipe, this lateral force caused bythe pipe movement is suflicient to tear the hanger from its fastenings- According to the present invention, such a ditllculty is entirely eliminated by provid ing a roller bearing for each individual pipe, so that the'pipes will move freely through thehanger and have no tendency to displace the same.

In the drawings which illustrate the inventionz-Figure 1 is a front elevation 01' the hanger with part of the cap broken awayf Fig. 2 is a side elevation of the hanger partly in section, on the line 22, Fig.1. Fig. 3 is partial longitudinal sec tion of the device, and shows a slight modification.

Referring more particularly to the drawings, 11 designates a base plate of any. suitable shape and size arranged for attachment to a wall by any suitable means, such as screws, passing through apertures 12." This plate is provided with a raised portion 13 along its longitudinal axis adapted to form a reduced bearing surface for the pipes.

A plurality of studs or posts 14 are provided projecting from, the plate, each suitably tapered at' its free end, as at 15, and provided with a shoulder 16 at the opposite Specification of Letters Patent.

end adjacent the base plate. A groove 17 is formed in each post near the free end thereof. A sleeve 18 surrounds each post extendlng from the shoulder 16 to the groove 17, as clearly shown.

The remaining member of the hanger is the cap or' closure member 19, which consists of a strip of material having a series of elongated apertures 20, each enlarged at one end, as at 21. These apertures correspond in number and spacing with the posts ll and are of such size in the enlarged portion 21 that the cap may be slipped over the ends of the posts. A slight longitudinal movement of the cap moves the portions 21 out of register with the posts, so that the edges of the apertures 20 engage in the grooves 17 and the cap is held against displacement. In practice, the cap will be applied to the hanger with the enlarged ends of the apertures down, so that the force of gravity will The hold the cap in its closed position.

cap may be provided With longitudinal ribs 22 for the purpose of ornamenting or strengthening the same, and also to provide a channel in which the projecting ends of the posts are wholly or partially concealed. Obviously, the cap member may be of tubular form, as shown at 23 in Fig. 3, thus concealingthe ends of the posts and the apertures, and providing suitable surface for ornamentation. It will also be understood that the uppermost post of the hanger need not be provided with a roller, if it carries no pipe, and may therefore be of a different form, as indicated in Fig. 3, so as to have the appearance of being continuous with the cap member.

The operation of the device is extremely simple, and it is believed will be readily understood and appreciated. The pipes rest each on a separate sleeve 18, as shown. As the pipes increase or diminish in length with the expansion and contraction due to temperature variations, they move in the hang ers. The weight of the pipe on the hanger is considerable, and therefore the frictional contact between the pipe and sleeve causes the sleeve to move with the pipe. In this movement, the sleeve merely rolls on the post, so that the hanger is not subjected to any stress beyond that incident to the Weight of the pipes.

Having thus described my invention, what I claim is 1. In a pipe hanger, a base, posts projecting therefrom, a shoulder at the inner end of each post, a groove at the outer end of each post, a revoluble sleeve on each post occupying the space between the shoulder and groove, and a cap member engageable in the post grooves retaining said sleeves.

2. In a pipe hanger, a base, posts there on, each having a circumferential groove adjacent the free end, a cap member having apertures therein'each larger at one end than 10 the other, the larger ends of the apertures being adapted for the passage of the posts. In witness whereof, I have hereunto set my hand, in presence of two witnesses.
